G'ruk
Gruk turns his crocodile head towards Elhdannis.  Brioc can sense his surprise at hearing the elf speak Druidic.  Brioc himself feels a bit uncomfortable with this as well, since Druids are forbidden to teach the language outside their order.  He has never heard the language spoken from a non-druid before.
G'ruk bows slightly to Ehldannis.  "Well, cousin, I think we may be able to work together.  I too, am after specific items.  Items related to my own heritage.  Long ago, before the ascent of man, and before these beast-men took over these caverns, we Saurials ruled this land.  I have reason to suspect the men built a city here over the ruins of a Saurial city.  I have found parts of this ancient city, I believe, but have been unable to find much.  Perhaps you could help me find more.  But we would need terms.  You could keep anything we find connected to man.  I would keep anything related to the Saurials."
[The tongues spell allows Ehldannis to speak and be understood by G'ruk.  I decided Druidic was the most logical choice for Ehldannis, since that is the only language he knows G'ruk speaks, and the one currently being used between G'ruk and Brioc.]
